TROPICAL RAINFOREST

GEOGRAPHY

• Places that the Tropical Rainforest are located are South America, Western Africa, South Eastern Asia.
• Tropical Rainforests cover less then 2% of the earth's surface

ABIOTIC FACTORS

• Water (All living things need water)
• Sunlight (The trees and plants need sunlight to grow)
• Climate (Determines how long it take a tree or plant to grow)
• Weather and precipitation (Affects how much water a plant will take in to grow)
• These things affect the trees and the animals that live there

GEOGRAPHY CONT.

• Tropical Rainforests are the most biologically diverse terrestrial ecosystems in the world.
• The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall.

BIOTIC FACTORS

• Producers: Plants (They make their own food so it determines what food the animals eat)
• Consumers: Animals (They eat a lot of the plants and grass)
• Decomposers: Fungi, Bacteria (They take part in what plants grow)

RUBBER TREE

• Bark: Bark on the rainforest trees is thin which prevents other plants from growing on them and supports evaporation from the access humidity

RUBBER TREE CONT.

• Leafs: The leafs have drip tips which help the plants shed the access moisture

RUBBER TREE CONT.

• Trunk: The trunks on rubber trees are long and straight, they don't branch out until they reach the canopy

ORCHID

• Leaves: Buttress (roots that grow overground) are thought to provide extra support for plants growing in spongy wet soils

ORCHID CONT

• Sunlight: Tropical plants take in what little sunlight is available, but orchids grow high up in the canopy where there is more sunlight

TOUCAN

• Toes: They have four toes on each foot, two facing forward and two facing backward, so they have a better grip on branches and resting spots

TOUCAN CONT.

• Beak: The beak takes up one third of its body weight, it's made from keratin which is a protein found in feathers. It allows the toucan to grow long and make it light weight

MANDRILL

• Thumbs: A major adaptation of the mandrill is its opposable thumbs allow it to grasp tree branches

MANDRILL

• Clavicles: The clavicles enable a mandrill to climb trees, walk more sufficiently, and allow functioning of the arms

COOPERATION AMONG SPECIES

• Elephants eat grass. Trees and shrubs in the rainforest help the grass grow. Therefore the shrubs and the trees help the elephant get food so that they can survive without hunger.
• .

COORPORATION CONT.

• A lion and a tiger work together to kill a deer so they they can both have meat for food

COMPETITION AMONG SPEICES

• A lion and a cheetah both eat Zebra. There is only one zebra but two species that want it. The lion and the cheetah will fight over the zebra.

COMPETITION CONT.

• A deer eats plants. A lot of other animals also eat grass. If the deer eats all of the grass there will be no more grass for the other plants and animals.

CLIMATE

• The climate of the tropical rainforest is very hot and moist.

CLIMATE CONT.

• The average temperature of the tropical rainforest is about 80°F all year round.

CLIMATE CONT.

• Fun fact: The temperature of the rainforest has never dropped below 64°F, and it rains about 160-400 inches each year.

CLIMATE FUN FACT

• The highest temperature in the tropical rainforest is 93°F.

CLIMATE CHANGE

• Climate change will affect tropical rainforests temperatures, the temperature will most likely increase.

CLIMATE CHANGE CONT.

• Changing rain patterns will affect the rainforests, water availability, biodiversity, agriculture, and human health.

TEMPERATURE

• The average temperature in the tropical rainforest is 68-93°F.

PRECIPITATION

• The average precipitation level in the tropical rainforest is 50-260 inches per year
